Consumer spending on organic food products has grown rapidly. Some claim that organics have ecological, equity, and health advantages over conventional food and therefore should be subsidized. Here we explore the distributive impacts of an organic fruit subsidy that reduces the retail price of organic fruit in the US by 10 percent. We estimate the impact of the subsidy on organic fruit demand in a representative poor, middle income, and rich US household using three analytical methods; including two econometric and one machine learning. We do not find strong evidence of regressive redistribution due to our simulated organic fruit subsidy; the poor household's relative reaction to the subsidy is not much different than the reaction at the other two households. However, the infra-marginal savings from the subsidy tend to be larger in richer households.
消费者对有机食品的支出增长迅速。有人声称,有机食品在生态、公平和健康方面优于传统食品,因此应该得到补贴。在这里,我们探讨了一项有机水果补贴的分配影响,该补贴将美国有机水果的零售价格降低了 10%。我们使用三种分析方法,包括两种计量经济学方法和一种机器学习方法,来估计补贴对美国代表性贫困、中等收入和富裕家庭的有机水果需求的影响。我们没有发现由于我们模拟的有机水果补贴而导致的明显的再分配现象;贫困家庭对补贴的反应与另外两个家庭的反应并没有太大区别。然而,补贴带来的边缘以下储蓄往往在富裕家庭中更大。
